Answer 2

To find:

Formula of Potassium Ferrocyanide by Criss-Cross method.

Solution :

Potassium Ferrocyanide is ionic coordination compound consisting of Iron as the central atom and Cyanide radicles acting as Ligands :

Steps followed in Criss-Cross method:

• We will note down the valency of each component of the compound.

• Then simply Criss cross the valency is and write down the compound in its simplest form.

Valencies of the following :

$1) \: K = > \: 1$

$2) \: \bigg \{ Fe(CN)_{6} \bigg \}^{4- } = > \: 4$

Now , Criss-Crossing the valencies :

$\therefore \: \:K_{4} \bigg \{ Fe(CN)_{6} \bigg \}_{1}$

$= > \: \:K_{4} \bigg \{ Fe(CN)_{6} \bigg \}$

So , final answer is :

$\boxed{ \red{ \bold{ \: \:K_{4} \bigg \{ Fe(CN)_{6} \bigg \}}}}$
